The Grand Palais – one of Paris’ most famous buildings – was the setting for the celebratory launch of Sonia Rykiel pour H&M.

The Palais was transformed into a Parisian fantasy land for around 2,000 guests.

Inside the glittering city it looked like a surreal theme park for adults.

The lingerie and knitwear collections were displayed on floats which emerged from a recreation of the Arc de Triomphe, with a Parisian funfair as backdrop.

The show started with Lily Cole straddling a 20ft horse head on board a float surrounded with many other model showing off the lingerie collection.

This was then followed by girls swinging out wearing lingerie and many other floats followed.

Kate Bosworth was one of the many guests.

The actress looked stunning wearing a nude Sonia Rykiel Spring 2009 dress with sequin embellishments and a large bow detail on the front.

I love the dress, but I’m not so crazy about the black satin pumps.

Eva Herzigova opted for volume, wearing a large feathered coat with a classic LB-sequined-D which is gorgeous.

The green bag works against her look and doesn’t blend that well.

The Sonia Rykiel pour H&M lingerie collection debuts in around 1,500 H&M stores worldwide from December 5, as well as the knitwear collection for women and girls, which will arrive in around 200 stores on February 20, 2010.

Can’t wait for the knitwear.
